    Concerned after rain

    Our pool was dug last week, steel put in on Saturday. Unfortunately we got more rain Sunday and Monday than expected and walls have collapsed. Before I unleash, I thought I'd post these pictures. I'm concerned. Is this normally the way to fix a collapsed wall? I know very little about construction. I'm working from home today hoping I see more being done so I can ask.

    Re: Concerned after rain

    That is not the best way to deal with the wall issue. Its not awful but its not good workmanship. They need to remove the peg board and place dobies (spacers) in so that the guinite fills the entire void. They may need to wire some dobies together to do it and it will take more gunite but that is the contractor's risk. You don't want to shoot gunite when there is standing water or mud. Wet or damp soil is ok mud is not. This needs another day or 2 to dry out. Also you want 2 inches clear below the rebar cage on the floor. They need to add significantly more dobies on the floor.

    The pool is enginnered to be constructed in undisturbed soil. A gap behind the wall is not undisturbed soil.

    Re: Concerned after rain

    Gunite is tentatively scheduled for Tuesday. Pre-plumbing isn't in yet. They said it still needs time to dry out. The boards is what worries me, but I don't know much.

    Re: Concerned after rain

    The problem with the boards, as gwegan mentions, is that there will be voids behind the gunite shell. And since those voids are below the surface of the general ground level, the soil there will eventually erode down into the void leaving holes under your decking. Boards are fine when used as a back support for exposed areas, but not below grade.

    Re: Concerned after rain

    I'm just going to cause more problems here. There is bonding wire wrapped around the rebar -- that is good. But I don't see clamps. The bonding wire must be clamped to the rebar with a listed clamp. That is code. And it must be clamped to the rebar in four different places distributed around the pool. A listed clamp looks something like this: Galvan JRD Bronze Alloy Lay-In Direct Burial Ground Clamp; 3/8 - 1/2 - 1 Inch, 10 AWG Solid-2 AWG Stranded - Crescent Electric Supply Company

    Re: Concerned after rain

    Ours failed due to the improper clamp type.

    Re: Concerned after rain

    My husband doesn't think they are done with the collapsed wall. I didn't get a response from my email, but I think he spoke with the project manager and said they still have the pack the wall. He didn't say anything about the boards though. So I don't know. I do know I will not hand over the next check unless I am happy. Maybe I am overreacting??

    On a happier note, here is our design:

    Re: Concerned after rain

    No you are not overreacting. This is pool building. It's different . Just be polite and ask questions. I like the design. It sounds like rough pluming the pool is next. Let's see what it looks like after that.

    Yea that's the correct clamp.

    Maybe the boards were just a quick fix to stop mud from coming into the pool, or to help with erosion.

    Re: Concerned after rain

    I would imagine it's a temporary measure to stave off a larger collapse.

    Your design looks great!

    Re: Concerned after rain

    My husband talked to the construction manager today (I never got a reply on Friday). Yes, it is a temporary fix. They wanted to let the water they couldn't pump out evaporate. They are coming back tomorrow morning first thing around 7am (if we do not get storms tonight...should stay north along the Tex/Ok border...fingers crossed). They will remove the boards they have there now, scrape out the wall/loose dirt and place forms. They will double check all the rebar to make sure they are properly set. I feel better.

    Re: Concerned after rain

    I guess it looks okay? I have never seen a gunite pool be built before, except on YouTube. My sister has a liner pool.

    Re: Concerned after rain

    Looks good, don't stress they will scrape down and clean the whole thing very well before plaster. Most any divot or hole including any they may make to tile or put return jets on will get filled with plaster. Water, water, water you almost can't over do it don't worry if you get a couple feet pooling in the deep end.

    Re: Concerned after rain

    Our instructions said to wait 24 hours to water and to water twice a day. Is that typical? Construction manager said once a day is fine. I think I will stick to at least twice. High temps are forecasted to be in the lower 70's. How long should they wait to tile...should they wait? He mentioned the tile was being picked up today.
